Davis hit a two-run shot off knuckleballer R.A. Dickey (6-5) to put Baltimore up 3-1 in the fifth inning. It was the 11th homer of the year for Davis, who led the majors last year with 53.

Norris (6-5) gave up one run and seven hits in 6 2-3 innings to win his third straight start. The right-hander extended an impressive run by Orioles starters, who have allowed two runs or fewer in 13 of the last 16 games.

After Toronto closed to 3-2 in the eighth, Zach Britton got three outs for his seventh save.
